Broker & Buyer Comments

This "well-secured" residential tower offers "sought-after amenities" including a "pool with swim programs" and fitness center, though some find the "management process Byzantine" with "lengthy board reviews." The "methodical approval process" and upcoming "neighborhood construction" may give pause, but the "solid amenity package" provides value. Note: "pool availability varies" due to community programs.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
